P0174 Code: 2024 Kia Sorento – What It Means & Cost to Fix

2024 Kia Sorento P0174 System Too Lean Bank 2

What Does P0174 Mean on Your 2024 Kia Sorento?

A P0174 code on your 2024 Kia Sorento means the ECM detected a lean air-fuel mixture on Bank 2. The 2024 Sorento offers a 2.5-liter four-cylinder (191 hp), a 2.5-liter turbocharged four-cylinder (281 hp), or a hybrid powertrain with a 1.6-liter turbo four-cylinder paired with an electric motor (227 hp combined). All are inline engines with a single bank, so P0174 may relate to sensor designation, but the lean condition needs attention.

Your 2024 Sorento is fully covered under Kia's comprehensive warranty. Take it to the dealership.
